the traveling movement of a carriage from Winding upon itself. I i i In the invention forming the subject matter of the prior application, a carriage is held in a predetermined position on an aerial track by means of a cable and a frictiondrum, but no device is embodied therein for preventing the runs of the cable fromoverlapping each other as the cable is wound on the friction drum. In the absence of such a device, the strands of the cable, as

they are wound onthe friction drum, will at times overlap and be brought intofrictional wearing engagement, thereby decreasing the life of the cable and interfering with the general efiiciency of the system. V

The present invention is adapted for use as an adjunct to the mechanlsm' disclosed in the prior application, and .it successfully prevents the overlapping of the runs of the cable, thereby eliminating a disadvantagewhich heretofore has greatly impaired the durability ofthe cable, and, moreover, re'-- sulting .in other advantages. i

operative relation to the friction drum which is adapted to be controlled by suitable brakemechan' ism. 'Fig. 4 is an elevatlon of the deviceshown in Fig. 3, certain parts of the rope" guide being in section. Flg. 5 is a plan view of anotherembodiment of the invention. Fig. 6 is anelevation ofthe structure shown in Fig. 5, and Fig. 7 illustrates a side view of a still further embodiment ofthe invention. Fig. 8 is a plan view illustrating another embodiment of the invention wherein a plurality of direction sheaves are employed in lieu of a single idler drum. i i

The cablewayillustrated in Fig. 1 of the drawings embodies two towers, A, A, an aerial track formed by a cable, B, a'carriage, C, adapted to travel on the aerial track, hauling. ropes or 'cables, D, D, cooperating with the carriage and adapted torraise, lower and transport a load carrying device, such as bucket, E, and engine, F, for rotating a suitable drum whereby cables, D, D, are operated, and a. controlling cable, G, at-

tached tocarriageyGufor the purpose of imnartingmovement to cable, G, by the motlo-n of carriage, C. The carriage'is provided with carryingwheels, .0, which are adapted to travel on the aerial cable, and, furthermore, said carriage is provided with direction sheaves, 0, over which. run the cables, D, D, for supporting and operating the load carrying device, E. Track cable, B,- extends through the towers, and is anchored at suitable points beyond .the line of the excavation, said track cable, B, spanning the excavation Cable, D, passes upwardly 7 over sheave, c, at theleft of the carriage, thence over a direction sheave, (Z, in tower, A, thence across the excavation to and over another direction sheave, d, in tower, A, and thence to the engine operated drum, D The other cable, D, passes from bucket, E,

upwardly .oversheave, c, at the' right of carriage, C, and from, thence cable, D,

passes over a direction sheave, in tower, A, and thence downwardly to the engine operated drum. Endless cable, G, has its respectiveends attached to the sides of carriage, C, and one length. .of said cable, G, passes ,over a sheave, 'g, in tower, A. The other length of said endless cable, G, passes around a drum, H, mounted in the upper partoftower, A. As shown in Figs. Sand 4, drum, H, is supported for rotation in tower, A, by a shaft, h, the latter being mounted in bearings, h, of a frame, H, attached to the tower in any suitable or desirable way.

According to the present invention the friction drum, H, is provided with a series of annular concentric grooves, 72. and said drum is provided,also, with a brake surface, a, with which cooperates a suitable brake, I, the latter being shown in the form of a band brake, the ends of which are connected with an operating lever, I, from which leadsan operating line, 2", see Fig. 1. When tension is placed on the operating line, '5, lever, I, is moved in a direction to apply band brake, I, for the purpose of locking drum, H, against rotation, whereby the drum arrests cable, G, and thetravel of carriage, C, thus locking the carriage against movement on the aerial track, B, against the pull of ca- I bles, D or D.

Cooperating with friction drum, H, is an idler drum, J the latter being mounted for rotation freely on a shaft, J, which is journaled in suitable bearings, j, of frame, H.

' The axis of shaft, J, for supporting the idler drum is at an angle to the axis of shaft, It, for the friction drum, H, and thus the idler drum, J, is so positioned with relation to friction drum, H, that the runs or Wraps of cable, G, are precluded from overlapping .extends between the drums.

each other on said friction drum, H. As shown, idler drum, J, is provided with a plurality of annular concentric grooves, j, and carriage controlling cable, G,. is wrapped first around friction drum, H, in one of the grooves thereof, then around idler drum, J, in one of its grooves, and then the cable is wrapped around drums, H and J, alternately, all as clearly shown in Figs. 3

. and 4:. The idler drum, J, thus cooperates with the friction drum and the cable so that the runs or wraps of said cable will be retained in the grooves of the respective drums, whereby the parts of the cable engaging with friction drum, H, are precluded from coming into contact with each other.

The frame, H, is positioned to inclose a part of drum, H, and a part of drum, J, together with that portion of the cable which The parts of the drums which project beyond frame, H, are, in a measure, housed within guards, K, K, see Fig. 3, at the respective ends of the frame. The members, K, K, composing each guard are fastened to an end portion of the frame, and they are united to a 1ne1n ber, k, which is braced by angle irons, k, see Figs. 3 and 4. As shown-in Fig. 4, inside rope guides, K are fastened to the frame,

H, or to the guards, K, K, whereby the guides K are positioned between the fric-I tion drum and the second drum for directing the runs or loops of the controlling cable in predetermined paths with respect to said drums. It is apparent that the guides K are adapted for frictional contact with said runs or loops of the cable so as to serve as retaining means by directing the path of the runs of the cable with respect to the grooves in the friction drum and the second drum.

The operation of the cableway shown in Figs. 1, 3 and 4: will be readily understood from the prior description taken in connection with the drawings. When the load carrying device is to be raised, carriage, C, is locked on the aerial track byapplying tension to the operating line, 71, so as to apply the brake and restrain the friction drum, H, and cable, G, from movement. To raise the load, cables, D, D, are wound on the engine operated drum until the load reaches a proper point below the carriage. To move the carriage to the right, operating cable, D, is slackened and cable, D, is coiled on the drum, the brake, I, being released so that the cable, G, will follow the movement of the carriage, C, toward the right. When the carriage reaches the point where the load is to be discharged, brake, I, is applied to friction drum, H, for the purpose of arresting the cable, G, and carriage, C, after which cables, D, D, are operated or controlled to lower the load and open the bucket. The cables may now be operated to raise the empty bucket, and by slackening on cable, 1), cable, D, may be operatedto haul the carriage and bucket to the left. When the carriage reaches the place where the bucket is to work, brake, I, is applied to the friction drum, thus, locking cable, G, and restraining carriage, C, from further movement, after which cables, D,D, may be slackened so as to lower the bucket.

The system illustrated in Fig. 2 of the drawings employs a boom, L, suspended by cables, Z, from a mast, M, the latter extending upwardly'from a series of pockets, m, erected on a pier, m, or the like. On the aerial track afforded by the boom, L, is adapted to travel a carriage, G, having sheaves for the reception of cables, D, D, for operating and controlling a bucket, E, the latter being operated to deliver a load to, or remove it from, a barge, 6. Cables, D, D, are fitted to sheaves, (Z, d, 6Z2, so as to lead to the engine controlled drums, as in the system heretofore described. Controlling cable, G, is operatively fitted to a sheave, g, and a friction drum, H the latter being controlled by a band brake, I which is operated by lever, I the latter being manipulated by the line, 2' substantially as heretofore described in connection with the cableway of Fig. l. The controlling cable is attached to the respective ends of carriage, C, and it is wrapped on friction drum, H and idler drum, J the latter being supported in cooperative relation to the cable and the friction drum. v r I Instead of arranging the idler drum for its axis to be at an angle to the aXis of the h friction drum, I may employ the arrangements illustrated in Figs. 5 and 6, wherein the friction drum is indicated at H and the idler drum is J .The shaft, J of the: idler drum is parallel to shaft, lb of the friction drum, said idler drum having annular concentric grooves, j, and the friction drum having similar annular concentric-grooves,

h The cable is wrapped alternately around the grooved friction drum and the grooved idler drum, and intermediate said drums, H3, J is a roller, 0. The intermediate roller is supported by a shaft, 0, parallel to shafts, J if, of drums, J H the periph. cry of said roller contacting with the peripheral surfaces of the friction and idler drums. The intermediate roller precludes the tension on the cable, G", from drawing the idler drum toward the friction drum so as to maintain said elements in proper rela-.

the shafts of which are parallel. Cable, G

is wrapped alternately around the friction drum and the idler drum, and intermediate said drums is a plurality of rollers, O, the

shafts of which are parallel to the shafts of the friction and idler drums. Said roll- 'ers are positioned on the respective sides of a line intersectingthe aXes ofthe friction and idler drums, and said intermediate rollers, O, have frictional contact with the peripheral surfaces of said friction and idler drums for the purposes hereinbefore mentioned. v I 7 While I have shown and described the idler drum as a unitary structure and as having a plurality of grooves,it is obvious that the same result (2'. 6., directing the runs of the cable in spaced order on the power drum) can be attained by the employment of a plurality of direction sheaves J 5 mounted on a suitable shaft J see Fig. 8,

so. as to have cooperative relation to the cable and thedrum on which said cable is wrapped for the purpose of imparting motion thereto.

Having this fully described the invention, what I claim as new, and desire to secure bv Letters Patent is: v '1. In a system for hoisting and conveying, the combination with an aerial-track, a loadsupporting carriage movable thereon, and power cables for imparting traversing movement to said carriage and for handling the load, of a friction drum supported in araised position relative to the track,;brake mechanism cooperatingwith the friction lable from a distant point, an idle second drum positioned adjacent to the friction drum and to said track, an endless control linggcable connected to the carriage and looped or wrapped alternatelyaround the friction drum and the second drum,said condrum, said brake mechanism being control trolling cablebeing independent of the power I,
